Overview
The Viewshine residential water meter utilizes non-contact ultrasonic technology to achieve high-precision metering and a broad measuring range. Without any moving parts, it effectively reduces pressure loss and delivers exceptional long-term stability. It supports a minimum flow rate detection of 2L/h. It also features outstanding resistance to impurities and magnetic interference, offering a design life of more than 12 years. With flexible vertical/horizontal installation, LCD display, and IP68 protection, this ultrasonic water meter is the perfect choice for residential water measurement.
